Feature: patroni api
We should check that patroni correctly responds to valid and not-valid API requests.
Scenario: check API requests on a stand-alone server
Given I start postgres0
And postgres0 is a leader after 10 seconds
When I issue a GET request to http://127.0.0.1:8008/
Then I receive a response code 200
And I receive a response state running
And I receive a response role master
When I issue a GET request to http://127.0.0.1:8008/standby_leader
Then I receive a response code 503
When I issue a GET request to http://127.0.0.1:8008/health
Then I receive a response code 200
When I issue a GET request to http://127.0.0.1:8008/replica
Then I receive a response code 503
When I run patronictl.py reinit batman postgres0 --force
Then I receive a response returncode 0
And I receive a response output "Failed: reinitialize for member postgres0, status code=503, (I am the leader, can not reinitialize)"
When I run patronictl.py switchover batman --master postgres0 --force
Then I receive a response returncode 1
And I receive a response output "Error: No candidates found to switchover to"
When I issue a POST request to http://127.0.0.1:8008/switchover with {"leader": "postgres0"}
Then I receive a response code 412
And I receive a response text switchover is not possible: cluster does not have members except leader
When I issue an empty POST request to http://127.0.0.1:8008/failover
Then I receive a response code 400
When I issue a POST request to http://127.0.0.1:8008/failover with {"foo": "bar"}
Then I receive a response code 400
And I receive a response text "Failover could be performed only to a specific candidate"
Scenario: check local configuration reload
Given I add tag new_tag new_value to postgres0 config
And I issue an empty POST request to http://127.0.0.1:8008/reload
Then I receive a response code 202
Scenario: check dynamic configuration change via DCS
Given I run patronictl.py edit-config -s 'ttl=10' -s 'loop_wait=2' -p 'max_connections=101' --force batman
Then I receive a response returncode 0
And I receive a response output "+loop_wait: 2"
And Response on GET http://127.0.0.1:8008/patroni contains pending_restart after 11 seconds
When I issue a GET request to http://127.0.0.1:8008/config
Then I receive a response code 200
And I receive a response loop_wait 2
When I issue a GET request to http://127.0.0.1:8008/patroni
Then I receive a response code 200
And I receive a response tags {'new_tag': 'new_value'}
And I sleep for 4 seconds
Scenario: check the scheduled restart
Given I issue a PATCH request to http://127.0.0.1:8008/config with {"postgresql": {"parameters": {"superuser_reserved_connections": "6"}}}
Then I receive a response code 200
And Response on GET http://127.0.0.1:8008/patroni contains pending_restart after 5 seconds
Given I issue a scheduled restart at http://127.0.0.1:8008 in 3 seconds with {"role": "replica"}
Then I receive a response code 202
And I sleep for 4 seconds
And Response on GET http://127.0.0.1:8008/patroni contains pending_restart after 10 seconds
Given I issue a scheduled restart at http://127.0.0.1:8008 in 3 seconds with {"restart_pending": "True"}
Then I receive a response code 202
And Response on GET http://127.0.0.1:8008/patroni does not contain pending_restart after 10 seconds
And postgres0 role is the primary after 10 seconds
Scenario: check API requests for the primary-replica pair in the pause mode
Given I run patronictl.py pause batman
Then I receive a response returncode 0
When I start postgres1
Then replication works from postgres0 to postgres1 after 20 seconds

When I sleep for 10 seconds
Then postgres1 role is the secondary after 15 seconds
Scenario: check the switchover via the API in the pause mode
Given I issue a POST request to http://127.0.0.1:8008/switchover with {"leader": "postgres0", "candidate": "postgres1"}
